The TEQSPORT Intake Manifold Spacer for 2010-2024 Toyota 4Runner is designed to improve real-world performance by optimizing the intake runner length of the factory intake manifold. Precision machined from billet 6061 aluminum, this spacer installs between the upper and lower intake manifold sections, increasing runner length and improving cylinder filling at lower engine speeds.
Unlike modifications that focus solely on peak horsepower, the TEQSPORT Intake Manifold Spacer is engineered to enhance performance where your 4Runner spends the majority of its time—below 4,500 RPM. By shifting the engine's powerband lower in the rev range, this spacer delivers noticeable gains in horsepower and torque throughout everyday driving conditions, improving acceleration, throttle response, and overall drivability both on and off-road.
The dyno sheet below perfectly illustrates the shift in powerband. While the overall power output change at peak isn't very large, the power and torque gained in the RPM range where your 4Runner is actually driven is significant. Whether you're climbing steep grades, towing a trailer, navigating technical trails, or simply merging onto the highway, the additional mid-range power helps your 4Runner feel more responsive and capable without sacrificing reliability or requiring extensive modifications.
